13 Claims.

Myinvention relates to prefabricated buildings. It has heretofore beenproposed to construct buildings having inner wall facings, such asplastering, secured to the walls by a sheet or sheets 5 of an-choring orclinching material fixed to the inner faces of prefabricated panelscomprising the Walls. This anchoring material has heretofore been in theform of individual sheets substantially coextensive with the panelscomprising the wall structure or has been in the form of continuoussheets extending over the area of several adjacent panels. As a result,the sheets of reenforcing material cause difficulty at the insidecorners when the plastering is applied, making an irregular and bulkycorner which it is difficult to plaster satisfactorily with an even andlong enduring coat of plaster, due to the necessary spacing connectionsbetween adjacent individual sheets when the latter ter- 20 minate in thecorner, and due to the need for the supplemental steel rod or rodsrequired to locate the sheet when a single sheet is carried around thecorner. This diiculty with a bulky corner is also emphasized by theusual provision of a felt strip in the corner over the metal framebetween adjacent panels to prevent condensation.

My invention has among its objects to eliminate the above difficultiesand markedly improve the corners formed in the interior of pre- 30fabricated buildings. A further object of my invention is to provide animproved construction whereby it is made possible to eliminate theprevious bulky inner corners and apply plaster to a wall havinganchoring or clinching means, such as sheets of reticulated metal, whilemaking a clearly defined and accurately formed longlived corner of theplastering. A still further object of my invention is to produce acorner structure which has the above advantages, and 40 the additionaladvantages of insuring a rm and even bond between the plaster and theWall members at the corners, and enabling the plaster to maintain theshape of the corners without tending to crack or pull away from theinner wall surface. These and other objects and advantages of myimproved construction will, however, hereinafter more fully appear.

In the accompanying drawing, I have shown for purposes of illustrationone embodiment Which my invention may assume in practice.

In this drawing,-

Figure 1 is a perspective view of an inside corner of a buildingVembodying my improve- 55 ments, the view being toward the ceiling;

Fig. 2 is a perspective view of a like inside cor ner, looking towardthe floor, and

Fig. 3 is a detail perspective view of the strips of fine mesh at thecorner junction in Figure 1.

In this illustrative construction, it Will be noted 5 that suitablechannel members I carry the usual insulating wall panels 2 and arearranged in a conventional manner together with a channel member 3 toforma corner post. A usual felt stripping i is supported on the innerexposed 10 surface of the metal of the channel members I forming thepost, in order to prevent condensation of moisture on the wall, -due todierences of temperature on the opposite sides of the same, While overthis felt strip my improved plaster supporting corner structure isdisposed.

In my improved construction, anchoring material 5, herein reticulatedmetal, is applied to the inner walland ceiling in continuous stripswhich are terminated at each inner corner; i. e., at corners formedbetween the outer walls and partition walls and between the side wallsand ceiling. The anchoring material 5 is spaced from the wall panels 2preferably by rods 6 which may extend into Lipper and lower channelsreceiving the corresponding edges of the panels, the upper channelsbeing shown at '1. Further, the adjacent edges of the different stripsof material overlie the felt strip il, preferably With these edgesadjacent one another but not overlying one 3o another, in such manner asthereby to minimize bulk in the corner.

In erecting the wall, when the felt stripping 4 has been placed asdesired, the anchoring material 5 is next applied and fastened to thepanels 35 by holding Wires 8, which may be inserted through suitableapertures in the insulating boards 2, forming the wall panels, andtwisted together over similar rods 6 on the outer surface `of the wall,in the same manner employed with 40 previous anchoring material carryingunits. After the wall panels have been erected in the frame, the exposedmetal has been covered with felt stripping, and the anchoring materialhas been fastened to the panels, in my improved construction, I nextapply a corner strip 9 of fine mesh anchoring material. This strip isusually bent at right angles along the center to fit within the cornerof the walls and extend over and cover the edges of the sheets ofanchoring material 5 along the entire length of the corner edges.

I also preferably hold the strip 9 in place by tacki'ng the same totherpanel boards 2, with short nails l0 or with other suitable fasteningmeans,

so as to form a rm base for plastering ll.

As shown in Figure 1, a strip 9 of like fine mesh anchoring material isalso placed along each junction between the reticulated metal 5 on theside wall and similarly disposed metal on the ceiling I2, as well asalong the length of the vertical corner between the side walls.

As shown in Fig. 3, the edges of the strips 9, 9 are preferablyoverlapped where they join with the side Walls so as to present aclinching surface for the plaster and form a clear and even surface tothe very point of the corner. It will be understood that the strips 9,9' may be intertted in any other suitable manner than by overlapping theedges, as long as the strips do not destroy the even surface of thecorner structure.

As a result of my improvement, it will be noted that not only is thesupport for the plastering increased in each corner, but that theplastering is more readily and easily applied to a corner on account ofthe gripping effect of the finer mesh of the extra strip of anchoringmaterial and because it conforms more closely with the corner. Notefurther that this results in a more accurately formed and smoothercorner where the plastering is applied and a corner which will not tendto crack or show other signs of an inadequate subsurface for theplastering. Attention here is particularly directed to the eliminationof unequal depths of plaster and of rounded or sagging corners whichmight result from the use of previous constructions which are difficultto make conform to sharp corners. Also, stopping and cutting the roll ofmesh at the corners facilitates the handling of the heavy rolls and thefastening of the mesh to the panels. These and other advantages of myimproved construction will, however, be clearly apparent to thoseskilled in the art.

While I have in this application specifically described one embodimentwhich my invention may assume in practice, it will be understood thatthis form is shown for purposes of illustration, and that the same maybe modified and embodied in other forms without departing from itsspirit or the scope of the appended claims.
